Jakob C. K. Soong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Low temperature firing (1800.degree.-2100.degree. F.) of barium titanate with flux (lead titanate-bismuth titanate-zinc oxide and boron oxide)
    Patent number: 4379854
    Abstract: A mixture of powders of barium titanate, a Curie point shifter and a lead titanate-bismuth titanate metal oxide flux which may be fired in a single step at 1800.degree. F. to 2100.degree. F. to produce a dense ceramic body with high dielectric constant. The ceramic is adapted to monolithic, multilayer ceramic capacitors. The low firing temperature minimizes the requirements of high temperature noble electrode material.
